Anyone using HRD on the TT Orion and if so, are you running it from the USB on the Computer or RS232 DB9 off the computer?Can't get the TT to talk to the computer (and vice versa) but someone mentioned you might have to use the USB port?

I've run my Orion II with both a USB/serial converter and a real serial port with a number of PC programs (DXLab, N1MM, N4PY, etc.) without problem. The only time I've run into a problem was with the Tentec supplied firmware upgrade program and that would function properly on my PC only with a real serial port.

But what doesn't make sense, is I can interconnect a Kenwood, ICOM, Yaesu to the computer Serial port and each and every time, HRD will take control of the radio, just not connect/talk to the TT, even with auto detect on the port and port speed. I am going to try a USB port next just to see if by some wierd chance, that sees the TT.

You didn't mention what version of HRD you are using, but this is a known bug in version 5 and the first version 6 release; it was fixed in the latest version 6.

Try connecting with Eagle as the radio selection first. If it connects, close that connection, restart HRD, and then create a new connection with Orion as the selected radio. You might have to do this a time or two...Once the connection is established with Orion as the selected radio, it should connect OK on each restart of HRD.

Well, master reset, NADA. I have to suspect a bad RS232 port on the radio (never had anything like that before). Can't imagine how that ever came to be. Computer connects to other radios, same port, HRD, without issue.
